To all whom it may concern:

Be it knownthat I, GEoRo-E'A. HOUSEMAN, a citizen of the United States,and a resident of Shreveport, in the parish of Caddo and State ofLouisiana, have invented certain new and useful Improvements in RadiatorCores; and I do hereby declare that the following is a full, clear, andexact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, which form apart of this specification. I

The device forming thesubject matter of this application is adapted tobe employed for cooling, heating or condensing, the structure being ofpeculiar utility when embodied in the form of a core for the radiator ofan automobile.

The invention aims to provide a cellular radiator core, the constituentmembers of which may be made out of a continuous strip, tubes beingformed, and each tube having an internal partition, a sinuous passagefor the liquid being provided.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the inventionappertains.

\Vith the above and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of arts and in the details of construction hereinafterdescribed and claimed, it being understood that, within the scope ofwhat is claimed, changes in the precise embodiment of the inventionshown can be made without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in perspective, a deviceconstructed in accordance with the invention, parts being broken away.

Figure 2 is a transverse section.

Figure 3 is a side elevation, the line 2-2 in Figure 3 indicating thecutting plane on which Figure 2 is taken.

In putting the present invention into practice, a strip of metal isprovided, and the same is bent upon itself to form the outer wall of atube, one side member of the tube bein denoted by the numeral 1, theside mem r 1 being prolon ed to form a side member 2, the side mem r 2being extended to form a side member 3. The side member 3 is bent andextended to fashion an S-shaped-partition 4 merging into aside member 5,which, in'its turn, is continued to constitute a side member 10overlapped upon the side member 3, "the side member 3 being disposedopposite to the side member 1 an the side member 5 being disposedopposite to the side member 2, as shown clearly in Figure 1 of thedrawin s. The side member 10 ofany one tube orms the member 1 of thetube next adjacent thereto, the construction being continued to anydesired extent, so that each bank of tubes is formed from a singlestrip. 1

Referring to Figure 2 and comparing that figure with Figure 1, it willbe noted that the vertical side member 5 is bulged in- \vardly to form achannel as indicated at 6', and the vertical side member 2 is bulgedinwardly to provide a channel as indicated at 8. These inwardly bulgedportions or channels (3 and 8 are not located opposite to each other,and, consequently, when one bank of tubes is placed against anotherbank, as shown in Figure 2, theinwardly bulged portim' or channel 6 ofeach tube stands opposue to and complements the noninwardly bulgedportion or rib of the adjacent tube in the same horizontal row, so thatthere results, between each of the vertical banks or rows of the tubes,a sinuous pass.(ge 11 through which the liquid to be coole passes. Theinwardly bulged portions 6 and 8*do not extend to the ends of the tubes,the ends of the tubes being left plain, as shown at 9, so that when onevertical bank of tubes is placed against another bank in assembling thecellular radiator core, the liquid .or water passa between said bankswill be closed at its en 5. Owing to the fact that the S-shaped artitionor fin is provided, a maximum con ucting surface is afforded, and thetube, at the same time, is reinforced and strengthened. The sinuouspassage shown at 11 promotes the operation of the device, in that noeddies result; no large body of liquid remains stationaryat any oneplace; and, sincethe water is forced to follow the sinuous path of saidpassa e and has no direct, straight path theret irough, the flow of thestream through the sinuous passage brings substantially all the water orliquid into frequent and continuing contact with the metal walls of thepassa e, thus insuring a rapid temperature interc ange and a quick lossof heat through cavities in the partition, of the wall of the tube beingbulged the radiation of the metal of the core. In

view of the fact that each bank of tubes is made of a single stri ofmetal, the bank may be of any desire extent,that is, there may as manyor as few tubes therein as the manufacturer may desire. After anydesired number of banks of tubes have been assembled as shown in Figure1, the same are immersel in a composition com osed of solderin flux andhot solder, a tlorough coatin oth inside'and out being the result, and te constituent banks of tubes being held together securely, The deviceaffords a large amount of heating surface with the expenditure of aminimum amount of mate rial, and a repair of the structure may be brouht about at any time without difliculty. I fiaim as my invention 1. Aradiator unit embodying a tube fashioned from a single strip bent uponitself to form, in a one piece structure, the outer wall of the tube anda partition connectin spaced ortions of the tube and \locat within t etube, the curved'to give the cross section and to form longitudinalconopposed portions inwardly, out of alinement with each other, inspaced relation to the ends of the tube and in alinement with theconcavities' of the partition, to form, in the completed radiae tor asinuous water passage.

2. A cellular radiator core comprising a plurality of tubular members,said tubular members being substantially rectangular in cross sectionand being arranged'in vertical partition bein" reversely' partition anshape inand horizontal rows, the several tubular members having theiropposed, vertical side wallsintermediate their ends formed to providelon itudinally extending complemental ribs an channels wherebyvertically dissed passageways are provided between adacent vertical rowsof tubular members, and each tubularmember being provided'intermediatesaid side walls with a longitudinally extending fin S-shaped in crosssection connecting its top and bottom walls.

3. A cellular radiator core com rising a plurality of tubular members,sai( tubular members being substantially rectangular in cross sectionand being arranged in vertical and horizontal rows, the several tubularmembers having their opposed side walls intermediate their ends formedto, provide complemental ribs and channels whereby vertically disposedpassageways are provided intermediate said walls, and an intermediate,

S-shaped in cross section connecting the top \and bottom walls of eachtubular member,

the several tubular members in each vertical row being fashioned from asingle strip bent upon itse f, to form in one piece the tubularstructure including said fin.

In testimony that I claim the foregoing as my invention, I aflix mysignature in the resence of two witnesses, this 10th day of arch, A. D.1923. r
